GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(909, 747) = 75447
GCD(909, 747) = ( 909 x 747 ) / 75447
= 909 / 747
= 909
Step2:
LCM(9, 745) = 6705
GCD(9, 745) = ( 9 x 745 ) / 6705
= 9 / 745
= 9
Step3:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
So, Greatest Common Divisor of 909, 747, 745, 138 is 1
